| Kev piav qhia |
Undecanedioic acid, nyob rau hauv daim ntawv ntawm cov hmoov dawb los yog flake, yog dibasic acids uas yog ib tsev neeg ntawm cov organic tebchaw, tseem hu ua 'long-chain dicarboxylic acids'. Undecanedioic acid yog alpha, omega-dicarboxylic acid uas yog nonane nrog ob pawg carboxylic acid ntawm txoj haujlwm C-1 thiab C-9. Nws muaj lub luag haujlwm ua metabolite. Nws yog conjugate acid ntawm undecanedioic acid anion. Nws tau pom zoo cov ntawv thov hauv corrosion inhibitors, kub yaj nplaum nplaum, kev ua haujlwm siab polyamides / nylon, cov dej ua haujlwm hlau, lubricant, nplaum, hmoov txheej, thiab lwm yam. |
| Chemical Properties | dawb mus rau lub teeb daj hmoov |
| Siv | Undecanedioic Acid yog ib qho bioactive compound pom nyob rau hauv Polygala tenuifolia cag uas yog siv los ua zaub mov ua haujlwm vim nws cov txiaj ntsig kev noj qab haus huv txaus nyiam. |
| Txhais | ChEBI: Ib qho alpha, omega-dicarboxylic acid uas yog nonane nrog ob pawg carboxylic acid ntawm txoj haujlwm C-1 thiab C-9. |
| Flammability thiab Explosibility | Tsis yog nplaim taws |
| Synthesis | Undecanedioic acid yog tau los ntawm reacting -nitro ketone thiab NaOH hauv MeOH.Rau cov tshuaj ntawm -nitro ketone (0.7 mmol) hauv MeOH (4.2 ml), 25 ml ntawm 0.5 M Na2HPO4 Hauv 1 N ntawm NaOH tau ntxiv thiab qhov sib xyaw ua ke tau ua kom sov ntawm 70 degree rau 1-4 h, tom qab ntawd Oxone (1.75 mmol) hauv dej (3 ml) tau ntxiv rau cov tshuaj txias (rt). Tom qab 4 teev cov sib tov tau diluted nrog brine (10 ml), acidified rau pH =2 nrog 10% tov ntawm HCl thiab muab rho tawm nrog EtOAc (3 x 20 ml). Cov txheej organic ua ke tau ntxuav nrog brine (10 ml), qhuav dhau Na2SO4 thiab evaporated kom tawm los ntshiab dicarboxylic acid. Fig Cov txheej txheem hluavtaws 2 ntawm Undecanedioic acid. |
| Qhov chaw | Undecanedioic acid yog ib yam khoom ntuj tsim nyob rau hauv Aloe africana, Phaseolus vulgaris, thiab lwm yam kab mob nrog cov ntaub ntawv muaj. |
